Viagra has been prescribed worldwide to treat men with erectile dysfunction. Clinical trials have shown that Viagra may cause various kinds of adverse effects include some central nervous system (CNS) adverse effects. Although extremely rare, toxic encephalopathy also can be one of those effects. This report presents a case of encephalopathy caused by Viagra in correlation with its radiologic findings. Its pharmacologic mechanism and potential effects on the biochemistry of the CNS are reviewed.

The emission of VOC from paint products constitutes a significant fraction of their emissions into the air (e.g., approximately 78% in the case of Korea). In this study, we attempted to investigate the major individual VOC components of paint products (e.g., out of 37 target compounds) using GC/FID method. Based on the analysis of 31 paint products currently available on the market, two types of TVOC were measured along with individual components. TVOC was measured as the paint plus thinner (TVOC(T)) and paint only (TVOC(P)). These TVOC concept was compared against the sum of individual VOC (such as ΣVOC). The concentrations of TVOC(T) and ΣVOC ranged between approximately 500~700 and 400~600 g L-1, respectively. Our results indicated that quantifiable VOC mainly consisted of toluene, ethylbenzene, and xylene. It was also found that 15 out of 31 paint products had the VOC contents exceeding the regulation limits. Moreover, the major fractions of TVOC in paint products were dominated by unidentified components. To reduce emission of VOC effectively, it is important to acquire a better knowledge on paint solvents through extended studies.

사물인터넷 환경에서 데이터 희박성을 고려한 유사도 측정 방법

정수연,손진혁,김영국 한국정보과학회 2019 데이타베이스 연구 Vol.35 No.3

The context-aware recommender system is a recommendation method considering the user's context in the existing method of the recommendation through the evaluation score of the users or the purchase history. As the Internet of Things become widely spread recently, the context-aware recommender system attracts the attention. However, the recommender system has a problem that is difficult to recommend to user with low volume of data. In addition, the sparse data problem of the recommendation method that reflects the context data is more serious than the existing recommendation method. Therefore, a recommendation method that can solve this problem is necessary. In this paper, we measure similarity by reflecting the number of items that are evaluated in common and apply context-aware collaborative filtering. As a result of the experiment, the proposed method is improved the recommendation performance compared with the existing similarity measurement and the proposed method is effective in the sparse data. 상황인지 추천시스템은 사용자가 평가한 점수나 구매이력을 통해 추천하는 기존의 방법에서 사용자의 상황을 고려한 추천방법이다. 사물인터넷이 보편화되면서 상황인지 추천시스템이 주목받고 있다. 하지만 추천시스템은 데이터가 적은 사용자에게 추천하기가 어려운 문제점이 있다. 또한 기존 추천 방법보다 상황정보를 반영한 추천 방법의 데이터 희소성 문제는 더욱 심각하기 때문에 이를 해결할 수 있는 추천 방법이 필요하다. 본 논문은 공통적으로 평가한 항목의 수를 반영하여 유사도를 측정하며 상황인지 협업필터링을 적용하였다. 실험 결과, 제안하는 방법이 기존의 유사도 측정 방법보다 추천 성능이 개선되었으며, 제안한 방법이 희박한 데이터에서 효과적인 것을 확인할 수 있었다.

Mouse 악성흑색종에서 Lipoic Acid가 항산화 효소계에 미치는 영향

정수연,김안근 대한암예방학회 2010 Journal of cancer prevention Vol.15 No.2

Reactive oxygen species (ROS) has been reported to cause DNA damage, lipid peroxidation, or protein denaturation and to be related also to the various diseases such as cancer, aging, cardiovascular disease,inflammation radiation injury, etc. through the different mechanisms. Being produced in the process of natural metabolism, ROS is controlled in the cell by the antioxidative enzymes of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), etc. Belonging to the sulfur containing compound,α-lipoic acid is a physioactive substance from the mitochondria energy metabolism, and its oxidized form (disulfide bonding in a molecule) can be reduced to two SH-free radicals that are distinguished in antioxidative effect. We have measured MTT assay, enzyme activity assay, and ROS level in order to examine antioxidative effect of the lipoic acid in the B16F10 murine melenoma cell. B16F10 cells were exposed to medium containing lipoic acid for a period of 24 h. Lipoic acid increased the activities of superoxide dismutase and catalase compared to those of the control, but decresed the activity of glutathione peroxidase. Lipoic acid also reduced ROS content in a dose-dependent manner. (Cancer Prev Res 15,152-157, 2010)

The purpose of this study was to examine the effect of experiential marketing on brand attitude and brand loyalty in family restaurants. Specifically, this study intended to identify the dimensions of experiential marketing in the restaurant industry and to examine the relationships among experiential marketing dimensions, brand attitude, and brand loyalty. Results indicated that there were four dimensions of experiential marketing: ‘Emotional service’, ‘Act and Relate’, ‘Logo and Advertisement’, and ‘Physical envi- ronment’. ‘Emotional service’, ‘Act and Relate’, and ‘Logo and Advertisement’ had an positive effect on brand attitude. ‘Emotional service’ and ‘Act and Relate’ had a direct effect on brand loyalty. The implications of the results were discussed

“Korean Wave” its origins can be traced back to 1996. Korea drama Korea to China as popular culture in China began to gain popularity. “Korean Wave” in China in the media in order to express this phenomenon was started using the word. The acceleration of Korean culture around the world, the concept of the new korean Wave was emerging. ‘New Wave’ of the Korean Wave in the country to embrace the local as well as take advantage of the high-dimensional reworking than the sightseeing, shopping, fashion and related industries in the area and the creation of substantial new flows, atmosphere. Korean Wave in China, Southeast Asia, starting think globally, compared with Korea’s pop culture phenomenon is starting a new phenomenon in the country is called New Wave singers in Korea, and to see the show or drama, Location Korea seeking to explore the fashion are means. Korea culture industry in the 21st century has become a very important factor. So until yesterday, and the other dimensions of the Korean Wave in the marketing and distribution of cultural content of the competitive capacity of the provision of a new strategy that can enhance the need for the duration of the Korean Wave to the content of all other investments, and thereby be expanded Wave to get out to strengthen the content. Improve the image of the country and the Korean Wave by linking to maximize the effect of the political, diplomatic, economic, and cultural exchange of cultural products through a preference for Korea’s national image of Korea should be linked to a crush on. Thus, Korea’s pop culture ‘Korean Wave world of fashion’ the narcissism of success, do not take on the ever-present risk of a variety As you remove them more robust and underlying viability of life to create a hearty South Korea's popular culture developed out will get out. 한류는 그 기원을 1996년으로 거슬러 올라갈 수 있다. 한국 드라마가 중국으로 수출되면서 중국에선 한국 대중문화 열풍이 불기 시작했다. ‘한류’는 중국 언론에서 이런 현상을 표현하기 위해 사용하기 시작한 단어였다. 또한 한류문화가 전 세계적으로 가속화 되면서 新한류라는 개념이 새롭게 등장하였는데 ‘新한류’는 국내에서 현지의 한류열풍을 적극 수용하고 활용할 뿐만 아니라 보다 차원 높게 재가공하여 관광, 쇼핑, 패션 등 연관 산업 분야에서 실질적 성과를 창출하는 새로운 조류, 풍조를 말한다. 한류가 중국 동남아 국가 현지에서 시작하여 전 세계적으로 일고 있는 한국의 대중문화 열풍인데 비해 국내에서 새로이 불고 있는 현상은 新한류라 하며 한국의 가수와 공연을 보기 위해 또는 드라마 촬영지를 답사하기 위해 한국을 찾는 열풍을 의미하고 있다. 한류는 21세기 한국 문화 산업에 있어서 빼놓을 수 없는 요소가 되었다. 따라서 어제까지의 한류와는 다른 차원에서 한류 문화콘텐츠의 경쟁력과 유통마케팅의 역량을 강화할 수 있는 새로운 전략의 마련이 필요하고 한류의 지속을 위해 무엇보다 한류콘텐츠에 대한 각종 투자가 확대되어야 하고 이를 통해 한류콘텐츠가 강화해나가야 한다. 한류를 국가 이미지의 개선과 연계시켜 한류의 효과를 극대화 시키고 정치 ․ 외교 ․ 경제 ․ 문화 등의 교류를 통해 한국 문화 상품에 대한 선호를 한국의 국가 이미지에 대한 호감까지 연계시켜야 한다. 따라서 한국의 대중문화는 ‘한류의 전세계적 열풍’이라는 성공의 자아도취에 취해 있지 말고 끊임없이 도사리는 다양한 위험들을 제거해나가면서 더욱더 기본기가 탄탄하고 생명의 성장력이 왕성한 한국의 대중문화를 만들어나가고 발전시켜나가야 할 것이다.
